`isFullScreen` of `UIWindowScene` has different available version between the dev doc and the xcode sdk

The isFullScreen attribute of UIWindowScene requires iOS 16+ on the dev doc. However, this attribute requires iOS 13+ in the Xcode iOS SDK (I'm using Xcode 15.0.0)

This would lead to an issue that you can write something like:

if #available(iOS 13, *) {
  windowScene.isFullScreen
}

and can pass the compilation, but crash on device using iOS 13~15.
